a staring point for guidelines for the management of suspected viral encephalitis
Submit responseOne of the issues arising from the review of management of suspected viral encephalitis(1) is the interpretation of cerebrospinal fluid(CSF) glucose content, and CSF glucose/blood glucose ratio(GR), given the overlap in clinical features between suspected viral encephalitis(1), meningitis of bacterial origin(including m tuberculosis aetiology)(2), and viral meningoencephalitis(3). What needs to be recognised is that the distinction between these entities(1)(2)(3) cannot reliably be made on the basis of the CSF glucose content(3)(4), or even the GR(5), notwithstanding the conventional wisdom that a GR of < 0.5 distinguishes between meningitis attributable to bacterial pathogens(including m tuberculosis) and viral meningitis(6). According to one study, which aimed to draw attention to suboptimal and highly variable practices in the management of herpes simplex type-2 meningitis in adults, a "low glucose(< 40 mg/dl)" content in the CSF could be a feature of herpes simplex meningitis(3). Although CSF glucose was not recorded as such in the report of a National Prospective Study of Infectious Encephalitis, 8% of 55 adults with herpes virus encephalitis were documented as having CSF "hypoglycorrachia", and the prevalence of this derangement was as high as 40% in 20 adults with varicella-zoster encephalitis(4). Other investigators have shown that varicella-zoster meningitis may be characterised by a GR as low as 0.4(range 0.4-0.73), and that, in enterovirus meningitis, GR may be as low as 0.26(range 0.26-0.76)(5). Accordingly, in the event that these observations are translateable to paediatric practice(where viral meningitis/encephalitis constitutes as many as 45% of microbiologically validated instances of acute central nervous system infection)(7), sole reliance on GR would be misplaced for differentiating between subtypes of meningitis and meningoencephalitis. What is also urgently required, is to put into practice the intellectual rigour of two recent studies of infectious encephalitis of various aetiologies(5)(7) so as to formulate robust guidelines for the management of children with suspected viral encephalitis.

Care planning in children with life-limiting conditions
Submit responseSir, in Nottingham, we have been operating a similar system to Fraser et al (1), for person specific planning for children with life limiting conditions since 2004. We have presented it at several national and international meetings (2-7).
Our system has 2 parts. The first part is the personal resuscitation plan (PRP) which describes in detail the interventions which are appropriate in the event of deterioration, whether sudden or gradual and considers the preferred place of death. This is a medical care plan and must be signed by the child's consultant. The second part of our tool kit is the 'wishes and choices' document which details the family choices regarding organ and tissue donation, post mortem and arrangements for care of the body after death. These two documents together make up the child's 'end of life' care plan, but unlike the authors we have found it important to approach families with them separately.
The PRP is a detailed emergency care plan which gives background information about the child's condition, plus symptoms and signs which would indicate deterioration as well as the specific interventions which are appropriate. This makes it relatively easy for the paediatrician to introduce to parents and carers of children with severe neurodisability, whether static or degenerative as soon as the child is having or is at risk of having life threatening events such as air way problems, chest infections, or prolonged seizures. It can be presented as a positive plan of best care, rather than dwelling on the plan for the child's death.
Our experience has been that families are keen to have an emergency care / resuscitation plan that promotes early and appropriate low level treatment and avoids inappropriate and invasive interventions, long before they are ready to discuss tissue donation and funeral arrangements. However making the PRP starts the conversations about what may happen and what choices are available, including the preferred place of death, and who can be there to provide support.
Feedback from local focus groups with hospital and community staff has emphasised the importance that the resuscitation plan is a medical care plan developed with the family and the care team, and family held, but signed as appropriate care by the child's consultant paediatrician. It then replaces the 'do not attempt resuscitation' form and will be followed by emergency services including ambulance staff.
Evaluation in 2006 showed that 19 out of 24 children on the community nurse case load with life limiting conditions had a plan and a prospective study in this same group of children showed that the plan was available and followed in 10 out of 11 emergency events, including seven deaths, with no admissions to the paediatric intensive care unit. Feedback from professionals and parents was that PRPs are useful and empowering.
PRPs do not time expire, but as the child's condition changes the resuscitation plan may need to change, and so must all copies. In our system the distribution list is part of the plan itself and the plan clearly states 'do not photocopy'.
We have found that while families are glad to keep the resuscitation plan with the child at all times and have copies widely distributed, they prefer not to carry around the 'wishes and choices' document, but to keep it more privately.
The Nottingham 'Personal Resuscitation Plan' and 'Wishes and Choices' templates can be found in Pfund and Fowler-Kerry (8).

Adverse effects of cranio-sacral therapy in infants
Submit responseAs your study states, little systematic research has been done on the effects of cranio-sacral therapy in crying infants. I would like to call your attention to serious side-effects to this form of therapy. Two well-proven cases of healthy infants that died during the therapy have been described, one in the Netherlands and one in Germany. It is important to tell parents about this potential side-effect. I am not surprised you were not able to find the Dutch article (to be found on PubMed): the title of the Dutch article has been translated incorrectly: diseased, rather than deceased!

Should we now stop cohort nursing babies with RSV?
Submit responseA major finding of this study was: "Infants with dual infections (RSV and hBoV) had a higher clinical severity score and more days of hospitalisation"
In our hospital, and many others round the world, babies with RSV infection are nursed in a room together and are not tested for Bocavirus. Should this practice now stop to prevent Bocavirus crossinfection increasing morbidity?

Managing frequent medical absences from school.
Submit responseWe were interested to read the paper by Jones at al1 on âFrequent medical absences in secondary school studentsâ. They conclude that âthis study should prompt education departments and their NHS partners to look more critically at the problem ⦠and to establish a system that provides more comprehensive assessment and treatment.â
Within Bolton PCT such a system has been designed in order to identify causes of frequent medical absences from school and to provide interventions aimed at supporting students to achieve an earlier and consistent return to school. Originally in Bolton (from the year 2000) referrals were made by the Education Social Work Department to a Senior Clinical Medical officer to undertake medicals on children with poor school attendance reported as due to ill health. This provided evidence to support an identified medical problem or for the LEA to issue a fixed penalties notice to the parent or carer. Since the issue of school attendance subsequently became a high priority policy concern for both the DfES and the DoH this service was re structured to develop an innovative Advanced Nursing Practitioner (with a school nursing background) led model for the evaluation of health issues for children and young people with poor school attendance. The main focus of the model was to enhance joint working between the advanced practitioner, Education Social Worker, schools and families. Changes have included a standardised threshold for referral (when attendance falls to 80%), agreed minimum information sets on referrals, agreed time frames for assessments and production of correspondence, holistic assessment, onward referrals, investigations and reintegration programmes to aide full return to school.
Over the last academic year 251 new referrals were received form the Education Social Work department (previously 55 a year). There were two peaks of referral (December 51, April 40). There were 120 referrals from primary schools and 131 for secondary schools. Referrals included 122 boys and 129 girls. Referrals to the service from 18 individual education social workers varied from 1 - 41 (median 14). The main causes of school absence were asthma, recurrent URTI, headache, sore throat, menstruation problems, chronic fatigue, skin problems, emotional and behavioural problems and inadequate provision for special needs within school. A variety of onward referrals were made including ENT, community paediatrics, dietetics, Young Carers, social care, occupational care, physiotherapy, CAMHs and two admissions to hospital. Support packages of care have been initiated for some together with supported reintegration plans to enable the young person to return to regular school attendance. Pathways are being devised for young people identified with âschool phobiaâ (jointly with CAMHs) and also a menstruation pathway for girls presenting with complex menstrual history.
In all cases of non attendance it is essential that preventative and early intervention should be seen as the cornerstone of multiagency working in order to ensure pupils right to education and to protect their health and well being. The redesigned service in Bolton has made good progress towards achieving these aims.

Editors should not be propagandists
Submit responseWe feel Dr Markovitch (1) was over critical of Hilton et al (2). Although we agree that there was a paucity of evidence to allow them to rebut Dr Wakefield’s suggestion that MMR could in some children cause autism, we believe that they still could have been clearer in reporting the full situation. The suggestion that the MMR vaccine should be given as its separate components came, not from a scientific paper, but as an announcement by a single researcher at a press conference. Within a month of the publication of the Lancet paper, a number of authors of the paper re-emphasised the importance of the combined MMR vaccine and that they had not proven a link between it and autism (3). It is these facts that should have been more strongly communicated, thus allowing people to attach the appropriate level of credence to Dr Wakefield’s views. If editors of journals had made more of this, healthcare professionals might have been better equipped for their discussions with parents.
We agree with Dr Markovitch that “…..they [editors] should offer honest accounts of best practice couched in language that generalist health care professional readers and the non-scientists writing for the public media can understand.” However, they should include all the relevant details including a balance that is truly reflective of the scientific evidence. The individual health professional is often unable to review the evidence themselves, through lack of time or access to the relevant material, and relies on journals such as those critiqued by Hilton et al to provide the information in a full but concise manner. Although this approach may not make for earth shattering headlines, it is responsible. We don’t suggest that editors should be censorious but it behoves them to couch unsubstantiated hypotheses in an appropriately cautious manner.

aneroid devices should be the preferred "new" sphygmanometers
Submit responseIt would be useful to ascertain whether or not the "new" sphygmanometer being compared with the Omron HEM 711(1) was an aneroid device, given the fact that those of us who lamented what we perceived to be an ill advised rejection of the mercury device welcomed the prospect that aneriod sphygmanometers "may replace the traditional mercury column in the healthcare workplace"(2). In the latter study, there were no significant differences(using the paired t-test) between the mercury standard and the aneroid device(Baum & Co), but the oscillometric device(Omron HEM-907)significantly(p=0.002) overestimated the systolic blood pressure(SBP) and significantly(p=0.0002) underestimated the diastolic blood pressure(DBP)(2). A later study study compared the Welch Allyn Tycos 767-Series Mobile aneroid sphygmanometer with the mercury device, and found no statistically significant difference for SBP but a significantly(p < 0.0001) lower reading for DBP using the aneroid device(3). Oscillometric devices, on the other hand, have proved to be almost universally unreliable. In one study, an evaluation of 9 devices showed that "accuracy appeared to deccrease at increasing blood pressure levels" with the potential consequence that "in treated hypertensive patients the necessary adaptation of treatment will not take place"(4). More recently, a comparison was made between the professional oscillometric device BpTRU, that had achieved an A grade of the British Hypertension Society validation protocol for both SBP and DBP measurement, and the standard mercury sphygmanometer(Baumanometer; WA Baum Co). A total of 5070 BP measurements were made using the two devices simultaneously. Unreliable readings(ie > 10 mm Hg difference in either SBP or DBP) were found in 755 patients. Unreliable readings occured in 15% of systolic and 6.4% of diastolic blood pressures(5). In view of the fact that "A decreasing arm circumference was a significant predictor of persistent UOBP(unreliable oscillometric BP)"(5), this observation might signify that oscillometric devices might be inherently unreliable in children References (1) Midgley PC., Wardhaugh B., Macfarlane C., Magowan R., Kelnar CJH Blood pressure in children 4-8 years: comparison of Omron HEM 711 and sphygmanometer blood pressure measurements Arch Dis Child 2009;94:955-8 (2)Elliot WJ., Young PE., DeVivo L., Feldstein J., Black HR A comparison of two sphygmanometers that may replace the traditional mercury column in the healthcare workplace Blood Pressure Monit 2007;12:23-8 (3) Ma Y., Temprosa M., Fowler S et al Evaluating the accuracy of an aneroid sphygmanometer in a clinical trial setting Am J Hypertens 2009;22:263-6 (4) Braam RL., Thien T Is the accuracy of blood pressure measuring devices underestimated at increasing blood pressure levels?

Decline in hospital MMR vaccinations: Are children being left unimmunised?
Submit responseI was interested to read Govindaraj et al’s audit showing a fall in the number of MMR vaccines given in their hospital over the last 2 years. Unfortunately there was no data to show what happened to those children initially referred to hospital for MMR, but referred back by the outpatient sister.
A study from New Zealand suggests that children inappropriately referred for MMR in hospital can be referred back and subsequently immunised in primary care [1]. However this was not our experience in Liverpool where 22 children, who had been advised by a health professional to have MMR in the community, were still referred to hospital [2]. This request for immunisation in hospital came from both primary care staff and parents.
It is important to ensure that children referred for MMR in hospital, but referred back to primary care, are subsequently immunised. Does Dr Govindaraj have any data to reassure us that the fall in the number of MMR vaccines given in their hospital is not due to children being left unimmunised in the community?

A/H1N1: Effectiveness of prevention in childhood
Submit responseThe question on how to manage the presence of the pandemic virus A/H1N1 in schools when the specific vaccine is not yet available is still open. Some countries have decided to postpone the opening of schools to avoid the epidemic peak, others have preferred to wait for the mass vaccination to contain the epidemic. WHO has recently issued a briefing note in which measures to be taken in school activities to limit the spread of virus A/H1N1 are detailed (1). In our experience, the education of students towards good hygiene practices has given interesting results. We are two recently graduated italian doctors who, in the period 6-21 July 2009, were accompanying - as a medical staff - an Italian group staying in Birmingham, composed by 163 students and 24 staff members. During this period, 7447 confirmed flu cases were notified in the UK(2), stating that this was an epidemic period for the new A/H1N1 virus. To avoid the contagion and its spread, some actions were taken in the small community: 1. Informing and educating all the guests, students and staff, on which good hygienic practices could help; 2. Distributing in strategic locations (toilets, meeting places) dispensers of antiseptic gel, to be used every time people had to shake hands, to touch objects, to eat or drink or after coughing e sneezing; 3. Stopping sport activities in the pool; 4. Isolating those with fever over 38°C, accompanied by flu-like symptoms, until the disappearance of symptoms. 5. Asking the intervention of NHS medical doctors authorized to prescribe antiviral drugs in every case of suspected flu. After adopting such measures, among the 187 Italian guests only 3 subjects had fever over 38°C and flu compatible symptoms within 7 days from arrival to the college, but only one was confirmed with swine-origin influenza A/H1N1 according to the protocol (3). Back in Italy, one additional girl had flu-like symptoms, and was subjected to laboratory tests which confirmed the presence of swine-flu infection. The application of preventive measures involved the consumption of 70 dispensers of antiseptic gel (18.7 mL/person/day). While our group was free to come back to Italy at the end of the programmed period, another group of 70 students had to be withheld for several days in the UK because 26 of them, in absence of hygienic prevention, fell down with flu in few days.
